Intraventricular hemorrhage (IVH) and hydrocephaly are the most common presentations of these accidents. Premature neonates less than 28 week age or 1000 gr have maximum risk of cerebrovascular accidents with prevalence of 30 percent. Early screening in high risk pregnancies with real-time ultrasonography can detect these lesions and affect on final prognosis. The purpose of this study is evaluation of brain ultrasonongraphic findings of 60 premature neonates born in Yazd University Hospitals, Yazd, Iran and relationship between these findings and delivery types.Methods: In this descriptive cross sectional study 60 cases of premature neonates (less than 37 week) who were born from January to July 2007 in Yazd hospitals were evaluated ultrasonographically to detect cerebrovascular accidents.Results: Among 60 premature neonates, 52(86.67%) were low birth weight and 8(13.33%) neonates weighted more than 2500gr. IVH was seen in five (9.6%) LBW neonates and hydrocephaly was seen in five (9.6%) LBW neonates. One LBW neonate (1.9%) had haloprocencephaly. Eight normal weight neonates had no abnormal ultrasonographic findings.Conclusion: All factors that induce preterm delivery and high risk pregnancies can increase cerebrovascular accidents in premature infants. Neonatal weight had most powerful relationship with neonatal ultrasonograohic findings.
